The Kelly-shell, Kellia Laperousii , Desh., 
shown in Fig. 6, PI. XIII, belongs to a little 
mollusk which shelters itself in clefts and holes, 
as the shell is thin and delicate. It has been 
mistaken for a borer, and it frequently lives in 
the empty holes of boring mollusks. The shell 
is smooth, oval, and light brown in color. It 
has one lateral and two cardinal hinge teeth, 
with a ligament between them. 
A pretty little shell, not half an inch long, 
may sometimes be found fastened to the rocks 
in concealed places. An enlarged figure of it is 
shown in Fig. 7, PI. XIII ; it is called La - 
zaria subquadrata , Cpr. It is strong, full, and 
marked by fifteen strong, rounded ribs, radiating 
from one angle of the four-sided shell. Its color 
is white, variously marked with brown spots. It 
is used in ornamenting shell frames. 
Cliione simillima , Sby., is found in the south- 
ern part of the State. Its length is two inches, 
and its breadth is nearly the same. The valves 
are very stiong and thick, finely sculptured in 
two directions ; the radial lines are rounded, and 
the concentric ones are thin and sharp. Heart- 
shaped lunule, conspicuous ; ligament, external, 
at the base of a broad depression ; cardinal teeth, 
strong, three in number ; pallial lines, entire ; 
color, brownish white, deeply stained inside with 
purple ; edge, slightly crenulated.
